青海省兴海县鄂拉山口多金属矿蚀变矿化特征及分带模式

Alteration and Mineralization Characteristics and Zonation Patterns of Aujiaoshan Polymetallic Deposit in Xinghai County, Qinghai Province

鄂拉山口多金属矿床位于柴达木盆地东南缘,是东昆仑造山带的重要组成部分,矿化带产于岩体与围岩接触蚀变带、不同岩性地层接触界面或地层中断裂破碎带内,兼有正接触带和外接触带2种蚀变矿化带。文章通过对鄂拉山口多金属矿蚀变矿化特征及分带模式进行初步分析,希望为该区找矿提供指示作用。

The elashankou polymetallic deposit is located in the southeastern margin of the Qaidam Basin, is an important part of the eastern Kunlun orogenic belt, mineralization belt in the rock and wall rock contact alteration zone and different lithologic stratigraphic interface or strata fracture fracture zone, which is the contact zone and the outer contact zone of 2 kinds of mineralization alteration zone. Based on the preliminary analysis of the alteration mineralization characteristics and zonation model of polymetallic ore deposits, this paper hopes to provide an indication for prospecting in this area.
